A recent study suggests that individuals who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass far faster than those who end conventional diet and exercise regimens.
Research printed in a leading health publication demonstrates that while overweight people can lose substantial amounts of their total mass while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals buying these treatments must be informed of the potential of rapid weight regain when the treatment concludes," cautioned expert Dr. Susan Jebb.
Such speed of regain suggests a return to original weight within about a year and a half.
Comparing Therapies
The research, which looked at dozens of trials involving over 9,000 of participants, contrasted the outcomes of the injectable medications with older methods.
Scientists point out that individuals who shed pounds through lifestyle changes alone usually have a more gradual creep back—around 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Experts believe the mode of action of the jabs explains the amplified regain.
These medications imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone levels far above than the body's typical production might result in the system to produce less of its endogenous hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication means appetite is no longer kept in check, making binge eating far more likely."
A Chronic Issue?
The NHS suggest the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, given the likelihood of weight regain, the treatment should be considered long-term.
This perspective is echoed by drug manufacturers, who state that the findings "emphasize the long-term character of excess weight," similar to managing conditions like high blood pressure.
Patient Accounts
People who have discontinued the jabs explain a intense return of appetite.
"It was like a switch activating and you become starving," said an individual.
The struggle is compounded if users have not adopted sustainable dietary or behavioural changes during treatment.
Widespread Use
Recent estimates suggest that millions of adults in the UK have tried these injections in the past year, with demand remaining high.
- Adoption is more common among females compared to men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, experts caution that while the jabs are effective tools for weight loss, they are not a permanent fix and maintained weight loss relies on combined lifestyle management.
